Abstract

PURPOSE:To improve an aeration effect by the decontamination action of microbes by providing a solid-liquid sepn. tank constituted of a filter layer extended with pipes and nets in a bed wall and providing a settling tank in the lower part of said wall adjacent to an inflow tank and a culture tank in the upper part thereof. CONSTITUTION:The sewage introduced through an introducing pipe D into a solid-liquid sepn. tank 4 is filtered of coarse dust by means of the PVC pipes 2 and nets 3 laid in the tank and is flowed into a settling tank 5. The sludge is discharged by the air fed to an air lift device provided in the tank 5 and the sewage flowing to the upper part is introduced through a pipe C into an inflow tank 7 and is flowed by the operation of a pump 8 through a pipe 9 into a fore stage aeration tank 10. Air from a pipe 22 is ejected from an air ejection cylinder, by which the sewage is aerated and th BOD therein is decreased. The sewage flows into a flow regulating cylinder 16, and the supernatant liquid flows through a flow pipe 15 into a culture tank 23 where the sewage is aerated by air.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for treating sewage generated in pig farms and the like. Conventionally, sewage treatment has generally been carried out using activated sludge method equipment, but most of them did not function satisfactorily and the purification effect was not good. In order to solve this problem, the present invention proposes a sewage treatment device constructed into a compact device that utilizes the purifying action of natural bacterial microorganisms and can maximize the aeration efficiency. An embodiment of the present invention will be explained with reference to the drawings. An introduction groove 1' is formed on the side wall of the elm, a vinyl pipe 2 is laid on the inner floor wall, and a thick anti-corrosion net 3 is stretched over it to form a filter vortex layer. Two solid-liquid separation tanks 4 are provided, an outlet B is provided at the bottom of the side wall of the solid-liquid separation tank 4, and a settling tank 5 is provided connected to the outflow port B. An air lift device 6 is installed, and the air pipe W is exposed to the bottom of the air lift device 6, and a
An inflow tank 7 is provided in contact with the settling tank 5 and the inflow 1vi/7, an inflow pipe 0 is provided in the inflow tank 5, and a pump 8 is connected to the inflow tank 7.
Connect the pipe 9 attached to the pump 8 to the previous stage aeration detection, install the sedimentation 4wu in the center of the 1111st stage aeration 4111110, and install the frame k at equal intervals around the bottom of the sedimentation tank 11.
Attach an air blowout tube at three locations, install an overflow notch in the upper part of the sedimentation tank and attach an outflow pipe stop, install a rectifier S16 in the center of the inside of the sedimentation tank, and install a rectifier S16 in the center of the rectifier tube. A flow pipe g is installed with the outlet facing upward, and the first stage aeration is
Attach the blower pipe addition to the pipe P installed outside the upper edge of the front aeration tank ■ than the blower installed in instant contact with l111D, fit the pipe 4 inside the tank to the pipe and connect it to the air jet tube. A sludge discharge pipe will be installed at the bottom of the sedimentation tank to discharge the sludge to the outside. @Culture is installed, culture detection and pre-stage aeration N10 are connected by installing a flow pipe stop, an air pump with an air suction pipe & is installed at the bottom of culture tank 2, and between culture tank 4v83 and aeration tank. Install the chemical injection pump i, branch the pipe attached to the pump d, and draw it into the culture tank and above the water surface of the aeration tank. ta
Set up an M-flow pipe in the center of the inside of the cypress, and connect the inflow pipe from the culture tank to the rectifier cylinder in the aeration tank, and sink 111! 'Attach an overflow notch to the top of #1g9 and aerate 411! Attach the drainage pipe to the horizontal wall of yaI and sink III! A sludge discharge pipe is installed at the bottom of the tank, a blower pipe is attached to the vibrator outlet provided on the outside of the upper edge of the aeration tank, and a frame ν is installed at three locations around the bottom of the aeration tank to drain the air. Attach the blowout tube and attach the tank pipe addition to the air blowout tube. In the diagram, the sewage inlet pipe is shown, E is the birch water pipe, and 7G is the support frame. With the above configuration, the sewage introduced into the solid-liquid separation tank from the sewage introduction pipe is filtered for bulky waste by the vinyl pipes 2 and nets 3, and flows into the sediment 41V 5 from the outlet, where it is precipitated. The sludge is discharged by the air sent to the air lift device installed in the tank, and the sewage that rises to the top flows in +1!
Air is introduced into Y7 through pipe 0, and when pump 8 is activated, it flows through pipe 9 attached to pump 8 and into the front aeration tank. The wastewater in the tank is aerated and the BOD decreases.
The U% sewage flows into the rectifier W116 from the pipe, and the sludge settles and is drained from the sludge discharge pipe. Flows into the culture tank 5, air is supplied by the air pump provided, and the agent is aerated by the water and air jetted out from the air pump to increase naturally occurring aerobic bacteria and reduce blisters that occur due to the effect of stirring. The sewage that has been injected from the pipe outlet to reduce blisters flows from the inflow pipe into the rectifier 41# of the aeration tank, and the muddy soil in the sewage containing undigested matter that is detected by culture sinks and is discharged as sludge. The supernatant water discharged from the pipe drain flows into the iaS from the overflow notch and is aerated with the air blown out from the rIJt vent, further digesting the undigested wastewater and stabilizing it by homogenizing the bacteria. Therefore, in this purification process, the wastewater immediately after passing through the solid-liquid separation tank has a BOD value of 3100 PPm and an 8B value of 760.
PPm is BOI) value 19PPm, 1 by the device of the present invention.
It has a purifying effect showing 38 value of 40PPm.
